Claas has announced the commercial release of the world’s first half-tracked tractors with full suspension.
Claas claims the Xerion is now among the most technologically advanced tractors available.
The machines have permanent 4x4 drive, all-wheel steering, continuously variable transmission and a choice of fixed, rotating or front-mounted cabins.
The new Trac TS variation, available on the Xerion 5000 (530 hp) and 4500 (490 hp) models, have four crawler units fitted with 762 mm (30”) tracks. The larger tracks are said to increase the machine’s footprint by 25% -- compared with the largest single tyre available – yet maintain an external width no bigger than 3m.
A pendular suspension system allows the crawler tracks to adapt to changing terrain and ensures a high level of driver comfort in combination with the existing cab suspension.
Both models now have MTU OM 471 Stage V engines that deliver higher torque at lower speeds. Peak torque has increased 6.1% to 2600 Nm on the Xerion 5000 and 4.3% to 2400 Nm on the 4500. And engine idling speeds have been reduced from 800 to 730 rpm, helping to reduce fuel consumption and unnecessary noise.
Both models have a three-way exhaust gas aftertreatment system. This includes a diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) technologies. The after-treatment system is located under the right side of the cab, avoiding the need for an external canister.
The service interval for the new engines has been doubled to 1000 hours, and the traditional dipstick has been replaced by a sensor; the oil level and top-up amount is displayed in the CEBIS terminal.
The cab now has an armrest with an integrated CMotion multifunction control lever and touchscreen CEBIS operating system. The 300 mm (12”) display gives a clear overview of all key machine settings and allows direct access to steering, transmission and hydraulics settings.
The function buttons on the CMotion control lever and the armrest can be freely assigned. Up to 20 different tractor/ implement combinations can be saved and directly accessed within CEBIS, which also includes a total of 10 different function buttons which can be freely configured with a range of control functions, depending on operator preference.
